(c)       Chattel Paper.  The Grantors will (i) deliver to Administrative Agent each original of each item of Chattel Paper at any time constituting part of the Collateral each time the aggregate value of all Chattel Paper in the Grantor’s possession exceeds $250,000, and (ii) cause each such original and each copy thereof to bear a conspicuous legend, in form and substance satisfactory to Administrative Agent, indicating that such Chattel Paper is subject to the security interest granted hereby and that purchase of such Chattel Paper by a Person other than Administrative Agent without the consent of the Majority Lenders would violate the rights of the Secured Parties.

(d)       Agreements.  Each Grantor shall use commercially reasonable efforts to ensure that each Material Agreement entered into after the date hereof (i) may be collaterally assigned to secure the Secured Obligations, and (ii) may, in the event of any exercise of remedies hereunder, be assigned to a purchaser in a foreclosure or other sale of all or substantially all of the assets of such Grantor or all or substantially all of the business or product to which such agreement relates (subject to assumption by such purchaser of all obligations under such Material Agreement),.  The provisions described in the preceding sentence need not be included directly in such Material Agreement, but may be agreed by the applicable Material Agreement counterparty in a separate letter agreement.

4.05     Remedies.  (a) Rights and Remedies Generally upon Event of Default.  During the continuation of an Event of Default that has not been waived in writing by the Majority Lenders in accordance with the Loan Agreement, subject to the other Loan Documents (including the provisions of Section 12 of the Loan Agreement), the Secured Parties shall have all of the rights and remedies with respect to the Collateral of a secured party under the NYUCC (whether or not the Uniform Commercial Code is in effect in the jurisdiction where the rights and remedies are asserted) and such additional rights and remedies to which a secured party is

entitled under the laws in effect in any jurisdiction where any rights and remedies hereunder may be asserted, including the right, to the fullest extent permitted by law, to exercise all voting, consensual and other powers of ownership pertaining to the Collateral as if the Secured Parties were the sole and absolute owner thereof (and each Grantor agrees to take all such action as may be appropriate to give effect to such right).  During the continuation of an Event of Default that has not been waived in writing by the Majority Lenders in accordance with the terms of the Loan Agreement, Administrative Agent may exercise, on behalf of all the Secured Parties, such rights and remedies of the Secured Parties described above; and without limiting the foregoing, but in each case subject to the Loan Documents:

(i)     Administrative Agent may, in their name or in the name of any Grantor or otherwise, demand, sue for, collect or receive any money or other property at any time payable or receivable on account of or in exchange for any of the Collateral, but shall be under no obligation to do so;

(ii)     Administrative Agent may make any reasonable compromise or settlement deemed desirable with respect to any of the Collateral and may extend the time of payment, arrange for payment in installments, or otherwise modify the terms of, any of the Collateral;

(iii)     Administrative Agent may require the Grantors to notify (and each Grantor hereby authorizes Administrative Agent to so notify) each account debtor in respect of any Account, Chattel Paper or General Intangible, and each obligor on any Instrument, constituting part of the Collateral that such Collateral has been assigned to the Secured Parties hereunder, and to instruct that any payments due or to become due in respect of such Collateral shall be made directly to Administrative Agent or as it may direct (and if any such payments, or any other Proceeds of Collateral, are received by any Grantor they shall be held in trust by such Grantor for the benefit of the Secured Parties and as promptly as possible remitted or delivered to Administrative Agent for application as provided herein);

(iv)     Administrative Agent may require the Grantors to assemble the Collateral at such place or places, convenient to the Secured Parties and the Grantors, as Administrative Agent may direct;

(v)     Administrative Agent may require the Grantors to cause the Pledged Shares to be transferred of record into the name of Administrative Agent or its nominee (and Administrative Agent agrees that if any of such Pledged Shares is transferred into its name or the name of its nominee, Administrative Agent will thereafter promptly give to the respective Grantor copies of any notices and communications received by it with respect to such Pledged Shares); and

(vi)     Administrative Agent may sell, lease, assign or otherwise dispose of all or any part of the Collateral, at such place or places as Administrative Agent deems best, and for cash or for credit or for future delivery (without thereby assuming any credit risk), at public or private sale, without demand of performance or notice of intention to effect any such disposition or of the time or place thereof (except such notice as is required by applicable statute and cannot be waived), and the Secured Parties, Administrative Agent or anyone else may be the

purchaser, lessee, assignee or recipient of any or all of the Collateral so disposed of at any public sale (or, to the extent permitted by law, at any private sale) and thereafter hold the same absolutely, free from any claim or right of whatsoever kind, including any right or equity of redemption (statutory or otherwise), of the Grantors, any such demand, notice and right or equity being hereby expressly waived and released.  In the event of any sale, assignment, or other disposition of any of the Collateral consisting of Trademarks, the goodwill connected with and symbolized by the Trademarks subject to such disposition shall be included.  Administrative Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for the sale, and such sale may be made at any time or place to which the sale may be so adjourned.

(vii)     The Proceeds of each collection, sale or other disposition under this Section 4.05, including by virtue of the exercise of any license granted to Administrative Agent in Section 4.04(b), shall be applied in accordance with Section 4.09.

(b)       Certain Securities Act Limitations.  The Grantors recognize that, by reason of certain prohibitions contained in the Securities Act of 1933, as amended, and applicable state securities laws, Administrative Agent may be compelled, with respect to any sale of all or any part of the Collateral, to limit purchasers to those who will agree, among other things, to acquire the Collateral for their own account, for investment and not with a view to the distribution or resale thereof.  The Grantors acknowledge that any such private sales may be at prices and on terms less favorable to Administrative Agent than those obtainable through a public sale without such restrictions, and, notwithstanding such circumstances, agree that any such private sale shall be deemed to have been made in a commercially reasonable manner and that Administrative Agent shall have no obligation to engage in public sales and no obligation to delay the sale of any Collateral for the period of time necessary to permit the issuer thereof to register it for public sale.

(c)       Notice.  The Grantors agree that to the extent Administrative Agent is required by applicable law to give reasonable prior notice of any sale or other disposition of any Collateral, ten business days’ notice shall be deemed to constitute reasonable prior notice.

(d)       No Assumption of Obligations.  Notwithstanding any provision in this Agreement or any other Loan Document to the contrary, the Secured Parties are not assuming any liability or obligation of any Grantor or any of its Affiliates of whatever nature, whether presently in existence or arising or asserted hereafter.  All such liabilities and obligations shall be retained by and remain obligations and liabilities of the applicable Grantor and/or its Affiliates, as the case may be.  Without limiting the foregoing, the Secured Parties are not assuming and shall not be responsible for any liabilities or Claims of any Grantor or its Affiliates, whether present or future, absolute or contingent and whether or not relating to a Grantor, the Obligor Intellectual Property, and/or the Material Agreements, and each Grantor shall indemnify and save harmless the Secured Parties from and against all such liabilities, Claims and Liens.

4.06     Deficiency.  If the proceeds of sale, collection or other realization of or upon the Collateral pursuant to Section 4.05 are insufficient to cover the costs and expenses of such realization and the indefeasible payment in full in cash of the Secured Obligations (other than

contingent indemnification obligations for which no claim has been made), the Grantors shall remain liable for any deficiency.

4.07     Locations; Names, Etc.  No Grantor shall (i) change its location (as defined in Section 9-307 of the NYUCC), (ii) change its name from the name shown as its current legal name on Schedule 1, or (iii) agree to or authorize any modification of the terms of any item of Collateral that would result in a change thereof from one Uniform Commercial Code category to another such category (such as from a General Intangible to Investment Property), if the effect thereof would be to result in a loss of perfection of, or diminution of priority for, the security interests created hereunder in such item of Collateral, or the loss of control (within the meaning of Section 9-104, 9-105, 9-106 or 9-107 of the NYUCC) over such item of Collateral, unless in each case 30 days’ prior written notice has been provided to Administrative Agent and such change is not otherwise restricted by the terms of any Loan Document.  No Grantor shall store its Collateral with an aggregate value in excess of $250,000 at any time with a bailee, consignee, or similar party, except for such bailees, consignees and similar parties as are disclosed on Annex I, unless in each case thirty (30) days’ prior written notice has been provided to Administrative Agent.

4.08     Private Sale.  The Secured Parties shall incur no liability as a result of the sale of the Collateral, or any part thereof, at any private sale pursuant to Section 4.05 conducted in a commercially reasonable manner and otherwise in accordance with the other Loan Documents.  Each Grantor hereby waives any claims against Administrative Agent, the Secured Parties or any of them arising by reason of the fact that the price at which the Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale or was less than the aggregate amount of the Secured Obligations, even if te Administrative Agent, the Secured Parties or any of them accepts the first offer received and does not offer the Collateral to more than one offeree.

4.09     Application of Proceeds.  Except as otherwise herein expressly provided and except as provided below in this Section 4.09, the Proceeds of any collection, sale or other realization of all or any part of the Collateral pursuant hereto, and any other cash at the time held by Administrative Agent or the Secured Parties under this Section 4, shall be applied by Administrative Agent or the Secured Parties (as the case may be):

First, to the payment of the costs and expenses of such collection, sale or other realization, including reasonable out of pocket costs and expenses of the Secured Parties and the fees and expenses of their agents and counsel, and all expenses incurred and advances made by the Secured Parties in connection therewith;

Next, to the payment in full of the Secured Obligations (other than contingent indemnification obligations for which no claim has been made) in such order as the Secured Parties in their sole discretion shall determine in accordance with the other Loan Documents; and

Finally, to the payment to respective Grantor, or its successors or assigns, or as a court of competent jurisdiction may direct, of any surplus then remaining.

4.10     Attorney in Fact.  Without limiting any rights or powers granted by this Agreement to the Secured Parties, during the continuation of an Event of Default that has not been waived in writing by the Majority Lenders in accordance with the Loan Agreement, Administrative Agent (and any of its officers, employees or agents) hereby is appointed the attorney in fact of each Grantor for the purpose of carrying out the provisions of this Section 4 and taking any action and executing any instruments that Administrative Agent may deem necessary or advisable to accomplish the purposes hereof, which appointment as attorney in fact is irrevocable and coupled with an interest.  Without limiting the generality of the foregoing, so long as Administrative Agent shall be entitled under this Section 4 to make collections in respect of the Collateral, Administrative Agent shall have the right and power to receive, endorse and collect all checks made payable to the order of any Grantor representing any dividend, payment or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same during the continuation of an Event of Default.

4.11     Perfection and Recordation.  Each Grantor authorizes the Secured Parties to file Uniform Commercial Code financing statements describing the Collateral as “all assets” or “all personal property and fixtures” of such Grantor (provided that no such description shall be deemed to modify the description of Collateral set forth in Section 3).

4.12     Termination.  When all Secured Obligations (other than contingent indemnification obligations for which no claim has been made) shall have been paid in full in cash, this Agreement automatically shall terminate, and Administrative Agent and the Secured Parties shall, upon request of Grantors, cause to be assigned, transferred and delivered, against receipt but without any recourse, warranty or representation whatsoever, any remaining Collateral and money received in respect thereof, to or on the order of the respective Grantor and to be released and canceled all licenses and rights referred to in Section 4.04(b), in each case, at Grantors’ sole expense.  The Secured Parties shall also, at the expense of such Grantor, execute and deliver to such Grantor such Uniform Commercial Code termination statements, certificates for terminating the liens on the Motor Vehicles and such other documentation as shall be reasonably requested by the respective Grantor to effect the termination and release of the liens on the Collateral as required by this Section 4.12, in each case, at Grantors’ sole expense.

4.13     Further Assurances.  Each Grantor agrees that, from time to time upon the written request of Administrative Agent, such Grantor will execute and deliver such further documents and do such other acts and things as Administrative Agent may reasonably request in order fully to effect the purposes of this Agreement and take all further action that may be reasonably required under applicable law (including the laws of each jurisdiction in which each Grantor or any of its Subsidiaries is organized), or that Administrative Agent may reasonably request, in order to grant, preserve, protect and perfect the validity and priority of the Liens created or intended to be created by the Loan Documents. Each Grantor will promptly cause any subsequently acquired or organized Subsidiary to take such action as shall be necessary to ensure that it is a “Subsidiary Guarantor” in accordance with Section 8.12 of the Loan Agreement.  The Secured Parties shall release any lien covering any asset that has been disposed of in accordance with the provisions of the Loan Documents.

Section 5.        Miscellaneous.

5.01     Notices.  All notices, requests, consents and demands hereunder shall be delivered in accordance with Section 13.02 of the Loan Agreement.

5.02     No Waiver.  No failure on the part of any Secured Party to exercise, and no course of dealing with respect to, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise by any Secured Party of any right, power or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy.  The remedies herein are cumulative and are not exclusive of any remedies provided by law.

5.03     Amendments, Etc.  The terms of this Agreement may be waived, altered or amended only by an instrument in writing duly executed by each Grantor and the Majority Lenders (unless the consent of a different group of Persons is required in accordance with Section 13.04 of the Loan Agreement).

(a)     The Grantors shall pay or reimburse Administrative Agent and the Secured Parties for costs and expenses in accordance with Section 13.03 of the Loan Agreement.

(b)     The Grantors shall hereby indemnify the Secured Parties, their Affiliates, and their respective directors, officers, employees, attorneys, agents, advisors and controlling parties in accordance with Section 13.03(b) of the Loan Agreement.

5.05     Successors and Assigns.  This Agreement shall be binding upon and inure to the benefit of the respective successors and assigns of each Grantor, Administrative Agent and the Secured Parties (provided that no Grantor shall assign or transfer its rights or obligations hereunder unless consented to in writing by the Majority Lenders in accordance with the Loan Agreement).

5.06     Counterparts.  This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may execute this Agreement by signing any such counterpart.

5.07     Governing Law; Submission to Jurisdiction; Etc.   (a) Governing Law.  This Agreement and the rights and obligations of the parties hereunder shall be governed by, and construed in accordance with, the law of the State of New York, without regard to principles of conflicts of laws that would result in the application of the laws of any other jurisdiction; provided that Section 5-1401 of the New York General Obligations Law shall apply.

(b)     Submission to Jurisdiction.  Each Grantor agrees that any suit, action or proceeding with respect to this Agreement or any other Loan Document to which it is a party or any judgment entered by any court in respect thereof may be brought initially in the federal or state courts in Houston, Texas or in the courts of its own corporate domicile and irrevocably submits to the non-exclusive jurisdiction of each such court for the purpose of any such suit, action, proceeding or judgment.  This Section 5.07(b) is for the benefit of the Secured Parties only and, as a result, no Secured Party shall be prevented from taking proceedings in any other

courts with jurisdiction.  To the extent allowed by applicable Laws, the Secured Parties may take concurrent proceedings in any number of jurisdictions.

(c)     Waiver of Venue.  Each Grantor irrevocably waives to the fullest extent permitted by law any objection that it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out of or relating to this Agreement and hereby further irrevocably waives to the fullest extent permitted by law any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.  A final judgment (in respect of which time for all appeals has elapsed) in any such suit, action or proceeding shall be conclusive and may be enforced in any court to the jurisdiction of which such Grantor is or may be subject, by suit upon judgment.

(d)     Service of Process.  Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 5.01.  Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.
